The Berg Balance Scale (BBS) measures balance in older people with impairment in balance function by assessing their performance on a number of functional motor tasks. It is a valid and reliable scale used in clinical practice and research. The scale consists of 14 items and takes between 10 and 15 minutes to complete. You will need a ruler, two standard chairs (one with arm rests, one without), a footstool, stopwatch, and a 15-foot walkway. If you are completing the assessment to measure change from baseline, a change in score of 8 points is needed to conclude that a genuine improvement of deterioration has taken place. A higher score is associated with a lower fall risk.
